What happens if I go over my plan's word limit?

Last updated: October 21, 2026

Each plan has its own overage rate. The rate is shown when you purchase the plan. Overage charges appear as an additional fee on your next invoice.

Each plan also has a monthly overage cap. Once your total usage reaches the cap, API requests are declined until you upgrade or your monthly usage resets. This protects you against unexpectedly high charges. We'll email you when you reach 80% of your plan's limit, when you reach the limit, and when you reach the overage cap.

For our monthly API plans, you can go over your plan by:

  • 300,000 words/month: up to 700,000 extra words (1 million total)

  • 1 million words/month: up to 2 million extra words (3 million total)

  • 2 million words/month: up to 4 million extra words (6 million total)

  • 5 million words/month: up to 10 million extra words (15 million total)

  • 10 million words/month: up to 20 million extra words (30 million total)

  • 20 million words/month: up to 10 million extra words (30 million total)

Annual and custom enterprise plans have overage terms set in your agreement. If you're unsure of your limit, email api@gptzero.me.
